来自印尼爪哇，Cikalong 的正品巨齿鲨牙齿

优质巨齿鲨牙，尖端完好，锯齿与牙釉质完好，

巨齿鲨（Megalodon，/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨大牙齿”，是一种已灭绝的鲭形鲨科物种，生活在约2300万年前至360万年前的始新世早期至上新世地层时期。此前被认为属于灯鳍鲨科（Lamnidae），并且是大白鲨（Carcharodon carcharias）的近亲。然而现今被归入已灭绝的 Otodontidae 家族，该家族在早白垩世与大白鲨分道扬镳。

尽管被认为是有史以来最大、最强的掠食者之一，巨齿鲨仅从零散的化石遗骸知之，它的外形和最大体型尚不确定。科学家对它更接近于体格更健壮的大白鲨、鲸鲨（Rhincodon typus）、抚鳃鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）之间有分歧。最新的较小误差范围的估计显示，最大体长可达约20.3米（67英尺），体重可达约103吨（114短吨）。

Authentic Carcharocles megalodon tooth from Indonesia, Java , Cikalong 

Quality Megalodon Tooth, with good tip, serrations , and enamel, 

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon), meaning "big tooth", is an extinct species of mackerel shark that lived approximately 23 to 3.6 million years ago (Mya), from the Early Miocene to the Pliocene epochs. It was formerly thought to be a member of the family Lamnidae and a close relative of the great white shark (Carcharodon carcharias). However, it is now classified into the extinct family Otodontidae, which diverged from the great white shark during the Early Cretaceous.

While regarded as one of the largest and most powerful predators to have ever lived, the megalodon is only known from fragmentary remains, and its appearance and maximum size are uncertain. Scientists differ on whether it would have more closely resembled a stockier version of the great white shark, the whale shark (Rhincodon typus), the basking shark (Cetorhinus maximus) or the sand tiger shark (Carcharias taurus). The most recent estimate with the least error range suggests a maximum length estimate up to 20.3 meters (67 ft),  weighs up to 103 metric tons (114 short tons)
